The former Germany international has been unable to work since April due to health problems, and despite a full recovery he believes he needs time away from Die Roten.
Matthias Sammer has quit his job as Bayern Munich sporting director, three months after being diagnosed with a brain illness.
Sammer has not worked since April due to the health scare, but says he is now fully recovered.
However, the former Germany international does not believe he is capable of fulfilling his duties as effectively as he had before falling ill.
"I feel very good. My health is restored," he said in a statement.
